According to their blog, the dev team will be releasing PwnageTool 2.0.2 sometime soon -- perhaps today. The release will be available through the built in updater in the current version of PwnageTool and via direct download for new users.

What to expect:

Ability to pwn iPhone firmware version 2.0.1

An updated version of Cydia with bugfixes

Update: Installer 4 will be included with this release!

No 3g unlock

The dev team also warns on their blog that you should not upgrade to firmware 2.0.1 via iTunes. Wait until PwnageTool 2.0.2 is released and upgrade to 2.0.1 with a custom ispw. Upgrading directly via iTunes will lessen the chances of you being able to unlock in the future. The dev team is still working on a 3g unlock solution.

From the Dev Blog:

Installer 4 and PwnageTool 2.0.2

We’ve just had word that our friends at RiPDev almost have Installer 4 (Beta) ready for public beta release, with that awesome news we’ve decided to include it in the PwnageTool 2.0.2 release, we are waiting for the software from them and we need to quickly test and add a small couple of changes that go alongside Installer.
